PRINTING-SURFACE HOLDER.

Specification of Letters Patent.

Patented .1 an. 5, 1915..

Application filed July 13, 1914. Serial No. 850,790.

To all whom it may concern:

Be it known that l HERMAN L. BORGER- sun, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented new and useful Improvements in Printing-Surface Holders, of which the following is a specification.

This invention relates to that class of printing surface holders known as a turtle or a fudge, being designed for holding any style of type in printing position upon the cylinder of a printing press.

It is desirable in newspaper practice to be able to print information from time to time in bulletin form without disarranging the printing surface of the cylinder of the printing press, and without the delay incident to stereotyping, etc. This is particularly true in connection with the printing of reports of all sporting events by the periods of play, such as innings of a baseball game, the quarters of a football game, periods of a polo game, etc., and the reports of all extras, such as cablegrams, telegrams, ctc., pertaining to murder, politics and up to the minute news items.

One of the objects of the present invention is to provide a device by means of which any style of type may be readily secured in position upon the surface of the cylinder of a printing press.

A further object is to provide a device of this character which will securely retain the type in place notwithstanding the high speed and centrifugal force developed in the operation of the cylinder.

A further object is to provide a stationary head and a movable type engaging slide in operative relation with said head, and means for holding said slide normally in engagement with the type.

A further object is to provide a device of this kind which will be made up of two parts and yet be strong enough to withstand the strains imposed thereupon in operation.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing :Figure 1 is a plan view illustrating my invention. Fig. 2 is a front view of the stationary head. Fig. 3 is a similar view of the movable slide. Fig. 4 is a front view of the slide and head in operative relation. Fig. 5 is a longitudinal sectional view with the slide in engagement with the type. Fig. 6 is a similar view with the slide withdrawn. Fig. 7 is a side view of the head. Fig. 8 is a similar view of the slide. Fig. 9 is a detail of the type engaging bead.

Referring to the drawing, 10 designates the base provided with a slot 11 to receive the screw usually employed for securing the device to the cylinder of a printing press. said screw not being shown. To one end of said base is secured an abutment 12 provided with a bead 13 having a knife edge 14 extending beyond shoulders 15 which are normally flush with the inner surface of the abutment. Secured to the other end of the base is a stationary head 16 provided with a plurality or sockets 17, and a depending guide portion 18. Slidably mounted upon the base 10 is a slide 19 having an upstanding abutment 20 arranged opposite the abutment 12 and provided with a bead 13 similar to that carried by abutment 12. Said slide is provided with a cut-out portion or opening 21 through which the guide 18 is projected, the movement of said slide being limited in either direction by said guide. The outer face of the abutment 20 is engaged by a series of plungers 22 located in the chambers 17 and normally pressed outward by springs 28. The heads of the plungers are provided with recesses to receive the forward end of the springs, the rear ends of the plungers being guided by sleeve-like extensions 24 surrounding the outer openings 25 of the bores 17. 1f desired the guide 18 may be provided with a chamber 26 and a spring-pressed plunger 27 similar to the plungers 22.

In operation, when it is desired to place the type 28 in position, the slide 19 is withdrawn by a suitable tool (not shown), and the individual types, or a linotype bar. conventionally illustrated at 28. may be place in position as indicated in Fig. 6. The slide 19 is then released, whereupon the plungers 22, under the expansion of the springs 23 force the slide 19 toward the abutment 12 to, engage the type as illustrated in Fig. 5. As the slide moves toward the abutment 12 the knife edges of the beads 13 penetrate the bodies of the contiguous type and firmly engage them, so that they cannot fall out unless the slide is moved to disengaging position. Thus it will be seen that the types are securely fastened in position and cannot be thrown out by the centrifugal force developed in the high speed of the cylinder. It will be observed that the head 16,

slide 19 and base 10 conform to the curvature of the cylinder. It will be further noted that the springs 23 are sufficiently heavy to force the slide 19 toward the abutment 12 just as soon as said slide is released, and that if any one of the springs should become broken, there still remains suflicient force in the remaining springs to retain the abutment 20 in engagement with the types.

My improved turtle is simple in construction, and may be readily applied to any of the machines now in general use without alteration, and being composed of few parts is readily manipulated and will not become deranged.

Having thus explained the nature of my invention, and described an operative mannor of constructing and using the same, although Without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what I claim is 1. A holder of the character described comprising a base, an abutment rigidly secured thereto, a head rigidly secured to said base in spaced relation to said abutment, a slide guided by said head and provided with an abutment, and means carried by said head and independent of the slide for yieldingly holding the abutment of said slide against outward movement.

2. A holder of the character described comprising a base, an abutmentv rigidly secured to said base, a head rigidly secured to said base and spaced from said abutment, a slide provided with an abutment, and guide portions engaging said head, said guide portions and said head having complemental means for limiting the movement of said slide, and means independent of the slide for yieldingly holding said slide away from said head.

3. A holder of the character described comprising a base, an abutment rigidly secured to said base, a slide provided with an abutment and spaced from the first mentioned abutment, spring plungers carried by said head and bearing against the abutment of said slide, to normally prevent retraction of the latter, and means for limiting movement of said slide.

45. A holder of the, character described comprising a base, an abutment rigidly secured thereto, a slide mounted to reciprocate on the top. surface of said base, and means supported independently of the slide for normally preventing retraction of said slide.

5. A holder of the character described comprising a base, an abutment rigidly secured thereto, a slide mounted to reciprocate on the top surface of said base and provided with an abutment, means for normally preventing retraction of said slide, and beads embedded within said abutments and provided with knife edges.

6. A holder of the character described comprising a base, an abutment rigidly secured thereto, a rigid head removably secured to said base and spaced from said abutment, a slide provided with an abutment, and means carried by said head and engaging said abutment to prevent retraction of the slide.

7. A holder of the character described comprising abase, an abutment rigidly secured thereto, a head rigidly secured to said base and spaced from said abutment, said head being provided with recesses, a slide provided with an abutment, and spring pressed plungers located within the recesses of said head and engaging said slide to normally prevent retraction of the latter.

8. A holder of the character described comprising a base, an abutment rigidly secured thereto, a rigid head removably secured to said base and spaced from said abutment, a slide provided with an abutment, means carried by said head and engaging said slide to normally prevent retraction of the latter, and means for limiting movement of said slide.

9. A holder of the character described comprising a base, an abutment rigidly secured thereto, a head rigidlysecured to said base and having a guide portion, a slide provided with an abutment and means for engaging said guide portion, and means carried by said head independently of the guide portion for normally preventing retraction of the slide.

10. A holder of the character described comprising a base, an abutment rigidly secured thereto, a head rigidly secured to said base and having a depending guide portion, a slide provided with an opening to receive said guide portion, and means carried by said head for normally preventing retraction of said slide.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
